High pressure hose having a fitting for attachment to a corresponding connector member

Abstract

In order to produce a high pressure hose having a fitting for attachment to a corresponding connector member, wherein the fitting comprises a connecting element for establishing connection to the high pressure hose and a coupling element for establishing a nipple/sleeve connection to the connector member, in such manner that a cost effective connection between the high pressure hose and the fitting can be established within a short period of time during the assembly thereof, it is proposed that the connecting element be in the form of a socket piece into which one end region of the high pressure hose is inserted and that the fitting form an interlocking closure assembly with the high pressure hose.

What is claimed is: 
     
       1. A high pressure hose having a fitting for attachment to a corresponding connector member, wherein: the fitting comprises a connecting element for establishing a connection to the high pressure hose and a coupling element for establishing a nipple/sleeve connection to the connector member,   the connecting element is in the form of a socket piece into which an end region of the high pressure hose is inserted, with the fitting forming an interlocking closure assembly with the high pressure hose,   the high pressure hose comprises a resilient inner tube that is surrounded by a braided sleeve or sleeve of woven fabric with which the fitting is in engagement, said sleeve being provided for absorbing tensile forces occurring in the high pressure hose, and   the braided sleeve has a twist angle of approximately 30° to 60°.   
     
     
       2. A high pressure hose having a fitting in accordance with claim 1, wherein: the coupling element comprises a hose stem which is resiliently deformable in the radial direction, and   the inner tube of the high pressure hose is inserted into the hose stem stripped of its braided or woven fabric sleeve.   
     
     
       3. A high pressure hose having a fitting in accordance with claim 2, wherein a sealing element is arranged between the high pressure hose and the fitting in a region that has been stripped of the braided or woven fabric sleeve. 
     
     
       4. A high pressure hose having a fitting in accordance with claim 1, wherein a sealing element is arranged between the high pressure hose and the fitting in a region that has been stripped of the braided or woven fabric sleeve. 
     
     
       5. A high pressure hose having a fitting in accordance with claim 1, wherein the socket piece and the coupling element comprise a one piece component of synthetic material. 
     
     
       6. A high pressure hose having a fitting in accordance with claim 5, wherein the component of synthetic material is an injection molding which is molded around the end region of the high pressure hose. 
     
     
       7. A high pressure hose having a fitting in accordance with claim 6, wherein the end region of the high pressure hose comprises at least one lateral opening which is engaged by the injection molding. 
     
     
       8. A high pressure hose having a fitting in accordance with claim 6, wherein one of the inner tube and an outer covering sleeve surrounding the braided or woven fabric sleeve is made of the same synthetic material as the injection molding. 
     
     
       9. A high pressure hose having a fitting in accordance with claim 8, wherein the end region of the high pressure hose comprises at least one lateral opening which is engaged by the injection molding. 
     
     
       10. A high pressure hose having a fitting in accordance with claim 1, wherein at least one projection is disposed on the inner wall of the socket piece. 
     
     
       11. A high pressure hose having a fitting in accordance with claim 1, wherein the fitting comprises a resilient expansion element which is insertable into the high pressure hose for enlarging the hose in the radial direction. 
     
     
       12. A high pressure hose having a fitting in accordance with claim 11, wherein the expansion element is in the form of a resilient ring which is insertable into the high pressure hose. 
     
     
       13. A high pressure hose having a fitting in accordance with claim 11, wherein the expansion element is in the form of an expansion sleeve which is insertable into the high pressure hose. 
     
     
       14. A high pressure hose having a fitting in accordance with claim 11, wherein the expansion element comprises a conical enlarging section. 
     
     
       15. A high pressure hose having a fitting in accordance with claim 14, wherein the expansion element is in the form of a resilient ring which is insertable into the high pressure hose. 
     
     
       16. A high pressure hose having a fitting in accordance with claim 14, wherein the expansion element is in the form of an expansion sleeve which is insertable into the high pressure hose. 
     
     
       17. A high pressure hose having a fitting in accordance with claim 1, wherein the fitting comprises an anti-kink device of synthetic material connected to the socket piece in a unitary manner.
